, Having reference to the drawings in detail, the

numeral I represents the top of a desk, table,

or other fiat object onto which a sheet of paper i6 is placed which isto receive the imprint negatively applied to the reverse side of amaster sheet or card anddisplay the same in positive form.

Where hereinafter reference is made to a sheet of paper it is intendedto include a post card or other card, or any object having a surfacecapable of receiving the imprint from a master sheet or card.

" .In Fig. '7 of the drawings, the master sheet or card is designated bythe numeral l1 and it may .l'iere'be stated that prior to placing themaster sheet or card upon the sheet of paper,'the area of the latterwhich is to receive the imprint is moistened by moving the moisteningelement of the device in contact with the face of the sheet .of paperand placing the master sheet or card upon the moistened area of thesheet of paper bodily as a unit over the surface to receive the imprintfrom the master sheet or card,'said two parts being connected togetherso that they have relative movement sufficient to control the deliveryof a solvent or other liquid fromone part 7 of the device to the other.

' In the particular embodiments of my invention shown in the drawings,the part I8 is in the form of a liquid-container serving as a hollowhandle for the device, while the part [9 is a housingtransversely-widened and pivotallyconnected to the adjacent or inner endof the liquid-container or handle. The latteris in the form of a tubeclosed at its inner end, as at 20, and open at its outer end to receivea closure or cap 2! which has an inwardly-extending flange 22 threadedhintosaid open end and between said cover and the edge of said tube awasher 23 is clamped. The cap therefore closes the open outer end of theliquid-container or handle in a water-tight manner. The closed or innerend of the liquidcontainer or handle is provided with a liquid escapepassage or opening 2a. The closed inner 'end of the liquid-container orhandle extends into the housing l9, which for convenience I term theThis housing or head is of parti-circular formation in cross section andit has an opening 25 formed in its peripheral wall 26 through which theclosed inner end of the liquid-container or handle extends.

The opposite side walls 27, 28 of this head 28 and the extended portionsof said side walls serve as lugs or bearings 32 between which amoistening-roller 32% is rotatably arranged, the roller being secured toan axle 34 having its ends journaled in said lugs or bearings. The frontend of the semi-circular re-entrant wall 33 also terminates a distanceabove the lower edges of said side walls for a purpose to appearhereinafter.

The tubular liquid' container or handle [8 is preferably flattened alongits lower portion or I underside at the inner end thereof, as at '35,and extending downwardly from said flattened portion are webs 36 andpivot lugs 37 formed as continuations of said webs; said webs and lugsbeing so spaced apart that their outer'sides lie in free moving relationto the inner surfaces of the side walls 27, '28, and pivots 32 ar passedthrough said lugs and through said side walls to pivotally connect theliquid-container or handle 18 and the housing or head It together.

Normally the lower edges of the webs 36 lie against the upper edge ofthe peripheral wall 26 forming the bottom of the opening 25 and thesewebs are so maintained by means of a combination spring-device and valveto be presently described.

Arranged for rotatable movement within the semi-circularroller-receiving pocket 3 l. is a pressure-roller 39 which is secured toan axle 4i] having its ends journaled in opposite side walls 2?, 28 ofthe housing or head [9. The axis of this roller is in rear of themoistening roller or element 33 and in planes forwardof and beneath thepivots 38.

The moistening-roller 33 and the pressureroller 39 are preferably formedof rubber, but any other material suitable for the purpose intendedmaybe used for these rollers. p

The pressure-roller is considerably larger than the moistening-rollerand normally the relationship of these rollers, when the parts are innormal position, is such that the pressure-roller will be in contactwith the support on which the device rests, while 'the.moistening-roller will be spaced from the surface of such part.

The inner closed end of the. liquid-container or handle is provided witha forwardly projecting liquid-discharge nozzle 4| through which theliquid-escape passage or opening 24 extends; said nozzle. having aninclined upper face 42 which is separated from the under side of a lip43 extending forwardly from the closed end of the'liquid-container orhandle l8. The liquidescape passage or opening 24 has its exit or outletat the inclined upper face 42 of the nozzle and the end faces of the lip43 are alined with the outer faces of the webs 38 and lugs 3'1 and thusoccupying the full width of the space between the side Walls 21, 28 ofthe housing or head.

thereof. Thus the area of the paper orother material to receive thematter by transfer from a master sheet will be evenly dampened and aperfect impression assured.

In the modification shown in Fig. 16, in addi tion to the liquid-escapepassag 24, I provide an air-inlet passage 54, preferably parallel withthe liquid-escape passage, and both of which open into a larger passage,55 at the outer end of the liquiddischar e nozzle 4|. In thismanner,:when. the combined spring device and valve is unseated in themanner shown in Fig. 16,, air enters the liquid chamber through theair-inlet passage 54 and assures a free flow of liquid from the vliquidchamber through the liquid-passage 24. This air-inlet passage 54 maybeutilized in the preferred construction and also in the variousmodifications; and although feeding of liquid fromthe liquid chamberwill occur without the use of an air-inlet passage, a more constant flowof liquid is assured by the use of the same.
